Greece Invoice MCP 🇬🇷 — How can my AI agent issue a myDATA τιμολόγιο (timologio) in Greece?
Use it in 60 seconds
Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, or any MCP-capable agent):
{
"mcpServers": {
"greece-invoice": {
"type": "http",
"url": "https://inv-gr.wishpool.app/mcp"
}
}
}
Nothing to install. Credentials, when you need them, travel as HTTP headers on each request and are never stored — see the threat model.
Or run it yourself
Would you rather not send production credentials to a server you do not control? Deploy this identical code to your own account and point your agent at your own URL:
git clone https://github.com/junter1989k-ai/greece-invoice-mcp && cd greece-invoice-mcp && npx vercel --prod

Remote MCP server that lets any AI agent issue Greece myDATA electronic invoices (τιμολόγιο / timologio) into the national AADE (ΑΑΔΕ) platform. It builds an AadeBookInvoiceType <InvoicesDoc> XML and transmits it under the merchant's own AADE credentials, returning the official MARK (unique registration number). Stateless, bring-your-own credentials, never stores anything.
Live endpoint: https://inv-gr.wishpool.app/mcp · Registry: app.wishpool/greece-invoice-mcp
Quick start
{
"mcpServers": {
"greece-invoice": {
"type": "http",
"url": "https://inv-gr.wishpool.app/mcp",
"headers": {
"x-aade-user-id": "<your myDATA user id>",
"x-aade-subscription-key": "<your Ocp-Apim subscription key>"
}
}
}
}
You register your ERP once on the AADE myDATA portal and receive a user id + subscription key (the developer/test rail issues them instantly). Requests default to the AADE test rail (no fiscal effect); add x-aade-mode: prod for the live rail. Your credentials never leave your side beyond the per-request header.
| Tool | What it does |
|---|
create_invoice | Build an AadeBookInvoiceType invoice from counterpart_vat + lines (net_value, vat_rate 24/13/9/6/4/17/0) and transmit to AADE myDATA /SendInvoices. Returns the official MARK, invoice uid, qr_url + computed VAT totals. |
query_invoice | Look up one of your own transmitted docs by mark via /RequestTransmittedDocs; found:true means AADE has it registered. Pass mark=0 to list from the start. |
Amounts are in EUR, VAT-exclusive per line. Greek VAT rates map to AADE vatCategory automatically: 24 (cat 1, mainland standard), 13 (2), 6 (3), 17 (4), 9 (5), 4 (6), 0 (7, exempt — needs a vat_exemption_category 1-31). invoice_type defaults to 1.1 (sales); use 2.1 for services, 5.1 for a credit note.
No cancel at the API level — corrections are issued as a credit note (invoice_type 5.1). Income classification (E3) is optional per line (income_classification_type / income_classification_category) — supply it if your accounting requires it.
Owner policy guardrails ride optional headers (x-agentpay-max-amount, x-agentpay-approval-above, x-agentpay-allowed-tools) — set by the human owner in client config; the agent cannot relax them.

- Send:
POST /SendInvoices (raw <InvoicesDoc> XML body) → <ResponseDoc> with statusCode + invoiceUid / invoiceMark / qrUrl
- Query:
GET /RequestTransmittedDocs?mark={n} → your transmitted docs with MARK greater than n

Safety
Pure stateless translation layer over the national AADE myDATA API. The user id + subscription key travel per-request in headers, nothing is stored. Privacy policy.
